## Summary by CodeRabbit

* **New Features**

desktop app and the system environment.
* Context menu actions (Cut, Copy, Paste) in the desktop app are now
localized according to the selected language.

regardless of spell check settings.

* **Localization**
* Added translations for "Cut", "Copy", and "Paste" in the context menu.
